TO. ALL WHOM IT` MAY CONGERN: y

Be it known that I, BENJAMIN FfCADY, of Chittenango, in-.the county ofMadison; and State of New York, have invented a new and valuableImprovement in Sleigh-Knees; and do hereby declare that the following isa full, clear, andvexact description of the construction and operationofthe same, reference being h ad to the annexed drawings, making a part ofthis specification', and to the letters and figures of reference markedthereon.

The objectof my invention is to construct a sleigh-knee that shall hemore simplel'in construction and more permanently useful than anysimilar device heretofore known.

To tbisfend, I first construct a rod of4 malleable or wrought iron, inthe form shown by the letter A of the drawings. The lower end of' thisrod passes through and ismade fast to the sleigh-runner, and theupperend passesthrough the top cross-piece and bottom board of thesleigh-body. The-sleigh-runner is represented by the letter B, the topcross-piece by C, and the bottom board by D, on the drawings.

Y Atthe top of the bottom board, I cut a threadon the rodA, and adjustto it a nut, as shown. This thread and nut'are shown at E. The lower endof rod A is made fast in the sleigh-runner by means of a head, G,bearing upward Vagainst a shoulder in said runner. I

It will readily be perceived that by means of saidtheadG and lthe nt andscrew E, the operator can tighten the rod at will, and may removeitaltogether with great ease.`

In order to protect said rod A, to give additional strengthA to thesame, and-furnish suitable bearings for the runner and cross-piece, Iconstruct a shield, marked H on the drawings, which fully insures to theknee all the benets named. The llanches a a clasp the upper side of therunner, and the flanches c c clasp the lower` side of the cross-piece.At the point 0,I leavean opening in the shield, for the insertionA of ascrew, by means of which the shield is always held firmly, and preventedfrom either a forward or backward movement under the cross-piece. Forthe purpose of cheap and rapid manufacture, I usually construct theshield H of cast iron. What I claim as my invention, and desire tosecure by Letters Patent, is

. A sleigh-knee having rod'A and shield H, constructed, combined, andarranged, substantially asdescribed,

as a new article of manufacture.
